To all whom z't, may concern Be it known that I, Gnnmr VAN DAAM, a citizenl of the United States residin at Buffalo, in the county of Erie, tate of` ew York, have invented a new and useful Con` vertible Coal Saver and Gas Burner, of which the following is a specification.

My invention relates .to convertible coal, or other fuel saver and gas burner for furnaces or stoves. The object is to provide a device adapted to deliver heated air to the combustion chamber of a furnace or stove, which by providing a suitable delivery end, and providing a gas supply nozzle at the intake end the devlce is also adapted to deliver and burn gas mixed with heated air in said combustion chamber. l

Referring to the drawings which illustrate, merely by way of example, suitablev means for effecting my invention- Fig. 1 is a side elevation in part section showing my device adapted to deliver heated air to the combustion chamber.

Fig. 2 is a plan view of the outlet end of same. y

Fig. 3' is an end elevation showing the air inlet regulator valve.

Fig. 4 is a side elevationof my device converted to deliver and burn gas in the combustion chamber.

Fig. 5 is a plan view of the gas burner end of the same.

Similar numerals refer to similar parts throughout the several views.

'lhe pipe 8 is exteriorly threaded throughout the greater part of its longitudinal extension. lt is adapted to be inserted in a suitable hole provided in the door frame or other part of a furnace or stove, and-is held in place by the nuts 7' threaded upon said pipe 8. The outer end of this pipe 8 is Haring or funnel shaped, as at9, and is rovided with a valve'or regulator plate 10 lield in place by screw 10', which permits a certain rotative movement of said valve plate to regulate the amount of air that may pass into said pipe 8. Upon the'inner end of pipe 8 is adjustably secured the end member 11, in F1g. 1, having an interior thread to cooperate with the exterior-thread of pipe 8.` This end member is provided with a bulb formation 12 having a substantially spherical chamber 18, and upon one or more parts of its periphery there is provided a substantially square t sage'.

lug or block 14, through which are provided the cross cuts 15 formin a correspondingshaped vent ,from sai chamber 13. Within this cross-shaped vent 15 is preferably inserted the wire gauze `or screen 16. l

Within the main extension of pipe 8 is removably inserted the spiral formation 17.

lin operation the air vin the chamber 13 becomes heated from the fire in the combustion chamber, and passes out lthrough the vent or vents 15 and, mingling with the gases resulting from the combustion of the fuel greatly facilitates the combustion of these gases in a way well understood in the art. As the heated air passes'out of chamber 13 through vent 15, fresh airis drawn in through pipe 8. The yspiral formation 17 tendsto retard the passage of air through pipe 8 to chamber 1.3, sothat the air becomes more thoroughly heated in said pas- Another function of the'spiral formation, is that, in retarding the'passage of air through pipe 8, it serves to make the flow more regular and less susceptible to fluctuations in' the draft connected with the furnace. ln fact the dow of air into and from chamber 13 is largely' due to the heating of the air in the bulb and to this extentis independent of the draft connected with the furnace, and stove.

Where it is desired to convert the device into a gas delivery and burning device, the spiral forntiatipn 17 is preferably removed. The end member ,11 is also removed and the burner member 18 is threaded on to pipe 8 as shown inI Fig. 4. This burner member 18 is so formed that its discharge end has its axis at right angles to the axis of its main extension. This discharge end is daring ory bell-shaped. Over this Haring discharge end is adjustably secured the plate 19 by means of the `threaded stud 20 secured in the lug 21 in the 'body of member 18 near 'its bend. etween the flaring end and the late 19 is 4formed ythe annular slit or I urner-vent 22, which may be made larger orsmaller as desired, by turning the plate 19 on its threaded supportingl stud 20.

At the flaring intake end 9, is provided a centrally dis osed threaded hole 23 inwhich is secure a suitable end or nozzle 24 of a gas supply pipe 25, controlled by the valve 26.

v cohination the plate or valve 10 ill@ is adjusted to admit the neceary supply of -air' to insure proper mixing with the gas ythe annular ventr 22. lThe burner end may be arranged to discharge upwardly, or may be inverted to discharge downwardly, in which latter case, that is, in the inverted position, the burning gas thoroughly heats theburner and the gas therein, thus preventing any moisture from escaping into the combustion chamber df the yfurnace or stove.

What I claim is 1. In a fuel saving device, the combinaltion of an air conductor, ,leading from the exterior to the interior of a combustion chamber,'a chambered bod disengageably secured to the inner end o said conductor and provided with a comparatively restricted discharge vent, and means for disengageably associating a fluid fuel supply with the air intake of the conductor.

2. In a fuel vsaving device, the combination of a air conductor, leading from the exterior to the interior 'of a combustion chamber, a chambered body disengageably secured to the inner end of said conductor and provided with a comparatively re stricted discharge vent, and means for disengageably associating a iiuid fuel supply with the air'intake of the conductor, so that the device is adapted to deliver to the combustion chamber, either heated air, or a mixture of heated air and Huid fuel, as required.
